Sparging (chemistry) (Redirected from Sparger) In chemistry, sparging, also known as gas flushing in metallurgy, is a technique which involves bubbling a chemically inert gas, such as nitrogen, argon, or helium, through a liquid. This can be used to remove dissolved gases (e.g. oxygen) from the liquid.
If a pressurized gas is forced through the fine network of pores in a porous metal sparger, very small diameter bubbles (0.5 to 10 micrometers) are produced to allow a high efficiency transfer of the contact gas to the liquid.
